QDOC'99 - A System for Automatic Cataloguing and Searching Document Bases

摘要

The costs of cataloguing a book manually for future access in a library exceed the costs of buying it by far. Therefore. libraries have a need for methods that support the automatic cataloguing of material. This paper describes the system QDOC'99 that implements the automatic extraction of bibliographical data from printed books into electronic catalogues; thereby, errors that originate from digitization of printed material are taken into consideration. The retrieval part of QDOC'99 comprises two approaches: one approach is directed towards a recall-oriented evaluation of queries; the other approach is directed towards a precision-oriented evaluation of queries. The performance of QDOC'99 was evaluated in an international contest on automatic cataloguing for which the results are given in the paper.
